Exam 27: Modeling with Simulation

Similar to mathematical and analytical models,simulation is restricted to using the standard probability distributions.

Setting up a probability distribution,building a cumulative probability distribution,and generating random numbers are:

A simulation is "Monte Carlo" when the elements of a system being simulated exhibit chance in their behavior.

The effects of OM policies over many months or years can be obtained by computer simulation in a short time.This phenomenon is referred to as ________.

The effects of operations management policies over many months or years can be obtained by computer simulation in a short time.What is this phenomenon called?

Simulation models that are based on the generation of random numbers may fail to give the same solution in repeated use to any particular problem.

A distribution of service times at a waiting line indicates that service takes 12 minutes 30 percent of the time and 14 minutes 70 percent of the time.This distribution has been prepared for Monte Carlo analysis.The first four random numbers drawn are 07,60,77,and 49.What is the average service time of this simulation?

A(n)________ is the accumulation of individual probabilities of a distribution.

One reason for using simulation rather than an analytical model in an inventory problem is that the simulation is able to handle probabilistic demand and lead times.

Complete the following table in preparation for a Monte Carlo simulation.The expected demand is 3.52.

A warehouse manager needs to simulate the demand placed on a product that does not fit standard models.The concept being measured is "demand during lead time," where both lead time and daily demand are variable.The historical record for this product suggests the following probability distribution.Convert this distribution into random number intervals.

Simulation allows managers to test the effects of major policy decisions on real-life systems without disturbing the real system.

________ is the attempt to duplicate the features,appearance,and characteristics of a real system,usually via a computerized model.

A distribution of service times at a waiting line shows that service takes 6 minutes 30 percent of the time,7 minutes 40 percent of the time,8 minutes 20 percent of the time,and 9 minutes 10 percent of the time.This distribution has been prepared for Monte Carlo analysis.The first two random numbers drawn are 53 and 74.The simulated service times are ________ minutes,then ________ minutes.

Complete the following table in preparation for a Monte Carlo simulation.

Random number intervals are based on cumulative probability distributions.

A distribution of service times at a waiting line indicates that service takes 12 minutes 30 percent of the time and 14 minutes 70 percent of the time.In preparing this distribution for Monte Carlo analysis,the service time 13 minutes would be represented by what random number range?

Simulation has numerous applications in modern business,but few of these are in the area of operations.

Which of the following is NOT a disadvantage of simulation?

Identify five applications of simulation.
